Wolverine LaunchPad runs out of RAM with CC3100 WiFi library

FR5969 LaunchPad doesn't have enough SRAM to fit the generous WiFi buffers:
```
/home/ebrundic/energia-0101E0013/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3/../../../../msp430/bin/ld: ScanNetworks.cpp.elf section `.bss' will not fit in region `ram'
/home/ebrundic/energia-0101E0013/hardware/tools/msp430/bin/../lib/gcc/msp430/4.6.3/../../../../msp430/bin/ld: region `ram' overflowed by 1128 bytes
collect2: ld returned 1 exit status
```

So I am going to make a pull request here to push the big WiFi.cpp buffers into FRAM for chips that have it.
